FAQ
Can a cavity hurt even if I cannot see it?
A cavity can start between teeth or under the surface, so you may feel pain before you see anything. Sensitivity, chewing pain, or a strange taste can be early clues. A dentist can find hidden decay with an exam and X-rays.
Do cavities always cause pain?
No, not always. Some cavities are small and do not hurt at first. That is why regular dental checkups matter, even if your teeth feel fine.
Can a cavity go away on its own?
No, a true cavity does not heal by itself. Early tooth decay may sometimes be stopped, but a hole in the tooth needs dental treatment. Waiting can make the problem worse and more painful.
When should I see a dentist right away?
See a dentist soon if you have strong pain, swelling, a bad taste, or trouble eating. These can be signs the decay is getting worse or may have reached the nerve. Quick care can help prevent a bigger problem.
